JOURNAL-BOX LUBRICATOR.

Specification of Letters Patent.

` Patented Dec. 1, 1914.

To all whom it may concern:

Be it known that I, JOHN DUTCHMAN, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Journal-BOX Lubricators,of which the following is a specification.

My invention relates to improvements in journal box lubricators, andamong the objects of my invention is the provision of a cellar orcontainer for the lubricants which can be inserted into the boX,-and ifnecessary, removed therefrom which will retain the lubricant in the mostadvantageous relation to the journal and prevent leaking of the oil;which will supply only the proper quantity for lubrication and insure aperfect distribution and which will ycomprise few parts to enhance thesimplicity and durability of the structure, and enable its production ata low price.

It also has for its object to provide simple means when the car to whichit is applied travels in either direction to elfectually feed thelubricant to the journal.

With these and other objects in view, .the invention broadly stated,lconsists of an oil container or cellar adapted to lit into the journalbox, and oil conveying and distributing means arranged in the cellar forlubricating the oil.

The invention further consists of a journal lubricator embodying novelfeatures of construction, arrangement and adaptation of parts forservice substantially as shown, described and claimed.

Figure 1 represents a longitudinal sectional view of a car journallubricator constructed according to my invention. Fig. 2 represents anenlarged vertical transverse sectional view, taken on line .Q -2,Fig. 1. Fig. 3 represents a perspective view of the novel mechanism forconveying the oil from the cellar or container to the journal, this viewbeing on an enlarged scale for clearness of disclosure. Fig. 4represents a longitudinal section through one of the oiling rollers, andFig. 5 is a sectional perspective view through oneend of the container.

Referring now to the drawings in detail, similar numerals of referencerefer to similar parts in the several figures.

The reference numeral 6 represents a portion of the frame of a car orlocomotive, 7 a portion of a wheel, 8 the aXle to which the wheel issecured, and 9 the brass of usual construction bearing upon the journalof said aXle, all of which parts are of any preferred construction.

I have designated the journal box by the nluneral l0 and this has theusual door opening 11 closed by the door l2, that portion of the frontwall 13 of ,said box directly beneath the door I preferably makeremovable to permit the ready insertion into and removal of my improvedoil container or cellar 14 from the journal boX. This oil container orcellar is of box-like or rectangular shape having straight or flatbottom 15, sidesl 16 and ends 17, but having its upper wall 18 madeconcavo-conveX in cross-section with a central longitudinal opening 19therein, and in this top wall at eachside of said central opening is aseries of oil apertures 20. The concaved upper surface of the upper ortop wall receives a portion of the journal and at each end of thecontainer or cellar an upwardly opening pocket 21 is provided, in whicht the plates 22 which have their upper edges curved to conform to thecircumference of the journal and are springpressed upwardly against thejournal by springs 23 coniined between the lower edges of said platesand the bottoms of said pockets. `These plates 22 serve to confine Inorderthat the container may be supplied with lubricant while positionedwithin the bearing boX, a feed pipe 24 is secured in the outer end wallof the container or cellar and at the point where this pipe enters,

The outer end Wall of the container or cellar is removably secured inplace to perinit of readily placing into said container or cellar thelubricant feed mechanism 2T and its supporting frame 2S. Said framecomprises a base member 29 formed of longitudinal and cross bars, orotherwise, and from this base member rise posts 30, preferably four innumber, around which are placed coil springs 3l that carry tvvo endvsupporting members 32 arranged transversely and provided with openings33, for a purpose to presently appear. The supporting frame 28 fitssnugly Within the container and cannot move laterally owing to the endsof the cross bars of the base meinber bearing against opposite sideWalls of said container.

Secured in the openings 33 of the j ournal supporting members 32 are thespindles 3l of oiling rollers l have provided two pairs of theserollers, ivliich are parallehtlie rollers of each pair beingindependently rotatable on a singlespiiidle. llhese rollers are coredout, as at 3G, and each has a circumferential groove 37 in which traveloil con ducting chains 38 which are endless and depend into the oilcontained in the cellar. rlllie circumferential grooves 37 of one pairof rollers are near the rear end of said rollers and those of the otherpair are near the front end thereof. Each roller has a series of spiraloil conveyingchannels 39 Which .extend from the circumferential .Grooveto the opposite end of the roller. rfliese channels trend in the samedirection and each has openings hl0 therein leading to the hollovvinterior of the roller.

ln operation, the oil Within the cellar is conveyed upward by the oilconducting chains 3i and delivered to the oiling rollers, the oil beingconveyed from the circumferential grooves 37 into the channels 3f),which in turn, during the revolution of the rollers, carry the oil ontothe surface of the latter, and as these rollers project through thecentral opening in the top Wall of the cellar and are held elevated bythe springs 3l they rotate in contact with the journal; in fact, arerotated by the journal; the oil beingtransferred, at least in part7 tothe journal and assuring a perfect lubrication thereof.

lt Tvvill be noted that the oiling rollers will revolve in the samedirection and according to the direction of travel of the train, andwing to the circumferential grooves 37 of one pair of rollers being nearthe rear ends of the rollers and those of the other pair being near thefront end, the oil is conducted into the spiral grooves of yone pairwhen the train moves in one direction and into the spiral grooves of theother pair When the train travels in the opposite direction. The journalis therefore properly lubricated regardless of the direction in whichthe train may be traveling. By the use of the spiral grooves leadingfrom the circumferential grooves in the rollers, the surfaces of theoiling rollers are oiled throughout at every point between thecircumferential grooves and the ends of the rollers at which the spiralgrooves terminate. The oil is also conveyed onto the surface between thecircumferential grooves of each roller and the adjacent end by reason ofthe side Walls of the circumferential groove being rounded, as clearlyshown. 'In this manner the oil is distributed evenly along the journal,and all surplus oil drips into the cellar through the central opening 19and the small openings 2O in the top Wall thereof. By reason of theoiling rollers being hollow, the surplus oil enters the hollow interiorthrough the small openings l0 therein and in part drips into the cellarWhile part finds its Way to the surfaces of the rollers to be deliveredto the journal.

Having thus described my invention, What l claim is,-

l. ln a journal-box lubricator, the combination with a journal and a journal-boX, of an oil cellar or container in said j ournal-box,

rtivo oiling rollers supported in said oil cellar or container held incontact with said jour nal, each roller having a circumferential groovenear one end and spiral oil conveying channels leading from saidcircumferential groove, the circumferential groove of one roller beingat the end opposite that of the other, the spiral oil conveying channelsof said rollers trending in the same direction, and a chain traveling ineach circumferential groove and depending into said cellar or container.
